Specification of Letters Patent. Patented Aug; 24 1915,

Application filed March 20, 1914. Serial No. 826,089. 0

To all whom it may concern Be it known that we, JOHN J. GAYNOR and PETER CARL LIEBER, citizens of the,

United States, and residents of Indianapo lis, county of Marion, and State of Indiana, have invented a certain new and useful Bottle-Capping Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to. the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to improve the construction of compensating mechanism in bottle capping machines in the type set forth in our applications, Serial No. 7 86,030, filed August 21, 1913, Serial No.

797,554, filed October 27, 1913, and Serial No. 806,908, filed December 15, 1913.

The chief feature of the invention consists in improvements by way of simplification of the compensating device for supporting the bottles and the like and particularly in the construction and means for controlling and operating the dog which initially receives the downward pressure of movement of the bottle support when the strain thereon becomes excessive. Also with the present construction all springs are dispensed with excepting the main supporting spring of the device. This not only simplifies the construction, but renders the same much more positive and certain in its operation.

The nature of the invention will be under stood from the accompanying drawings and the following description and claims:

In the drawings, Figure 1 is a central vertical section through a bottle support and the means on which it is mounted, in the bottle capping machine, the parts being in inoperative position. Fig. 2 is a cross section on the line 22 of Fig. 1. Fig. 31s a section on the line 33 of Fig. 1. Fig. 1 is a section similar to that in Fig. 1, showing the parts in operative position.

In the drawings there is shown a bottle support 15 which is screwed on to the upper end of the bar 16 around which there is a spiral supporting spring 17 lying between a collar 18 under a pin 19 through said bar 16 and the upper end of a tube 20 which surrounds the lower part of the bar 16. The spring 17 tends to hold the bottle supporting means elevated, but the following construction is provided for resisting the downward movement of the bottle support when the pressure on the bottle while being capped 7 becomes excessive. The lower end of the bar 16 has a recess 25 in one side with ashoulder 26 projecting from the inner surface of the bar 16 into said recess. Said shoulder is normally adapted to rest upon and is supported by a shoulder 27 on a dog 28 which is fulcrumed between its ends on a pin 29 extending transversely and mounted in the tube 20. The upper end of the dog 28 extends outwardly through a slot 30 in the tube 20 and in position to be engaged by the lower end of the spring 17 so that the downward pressure of said spring tends to return said dog after it has been operated to nor mal position and hold it there.

In operation the parts are normally as shown in Fig. 1, with the bar 16 supported by the dog 28. The spring 17 holds the dog in its supporting position. When excessive pressure is brought down upon a bottle being capped, it will force the bar 16 downward and cause the shoulder 26 of said bar to slip off the shoulder 27 of the dog, as seen in Fig. 4. As soon as the pressure is relieved on the bottle support, the spring returns the 1 bottle support to the upward position and also forces the dog into resisting position. The upward movement of the bottle supporting means is'limited by the projection 31 from the bar 16 under the pin 29 engaging said pin so that said pin serves as a stop.

The invention claimed is:

1. A bottle capping machine including a bottle supporting means having a bar, a tube in which the lower end of the bar extends, a dog fulcrumed-between its ends in said tube and arranged to resist the downward move ment of said bar, and a spring tending to support said bar and bearing on one end of said pivoted dog and holding said dog in resisting position.

2. A bottle capping machine including a bottle supporting means having, a bar with a shoulder thereon near its lower end, a tube in which the lower end of the bar extends, a dog pivoted between its ends in said tube and having a shoulder on one end thereof for engaging the shoulder of the bar and resisting the downward movement of the same, and a spiral spring tending to support said bar and pressing on said dog so as to extending bar having a recess in one side thereof and a shoulder near its lower end, a

tube'in which the lower end of said bar extends, a doglocated in the recess in said bar and having a shoulder to engage the shoulder on the bar and with the opposite end of a the dog projecting through a slot in said tube, a pin mounted in said tube for 111- cruming the dog between its ends, and aspi- 10 ral spring surroundmg sald'bar and resting upon the outer end of said dog, substantially as set forth.

In witness whereof, wehave hereunto affiXed our signatures in the'presenee of the witnesses herein named.
